Abstract: A trailing edge flap assembly for an aircraft wing includes at its rearward end upper and lower surfaces terminating in a trailing edge portion. The assembly has a flap (15) is located in a stowed position during normal flight. A mounting beam (18) is located to the lower surface (12) of the wing, extending rearwardly thereof and below the flap (15) A carriage (23) is in rolling engagement with longitudinal guideways (53) on the mounting beam (18). To actuate the flap (15), at or about the rearward extremity of the mounting beam (18), there is provided an actuator mounting bracket (21), a rotary actuator (52), and lever arms (27, 28) associated with the actuator about a common substantially transverse axis of rotation.The lever arms (27, 28) extend upwardly and terminate adjacent the undersurface of the flap (15), in a pivotal attachment (22) forwardly extending actuator links (25, 26) pivotally interconnecting the lever arms (27, 28) and the carriage (23). The flap (15) is supported by means of first link (33) interconnecting the carriage (23) to a forward portion of the flap (15), and a second link (36) interconnecting the actuator links (25, 26) to a more rearward portion of the flap (15). Location of a powered actuator (52) at the rear extremity of the mounting beam (18) in direct engagement with an actuating lever (27, 28) in close driving engagement with the flap (15) is both efficient and reduces power requirements.

Abstract: A fault tolerant computer system includes a fault tolerant data processing module which has means for detecting and cor­recting errors in the operation of the data processing module to maintain a high degree of data integrity. Data transmission con­trol devices control the transmission of all data to the fault tolerant data processing module and the receipt of all data into the fault tolerant data processing module. Input/output termi­nals are coupled to the data transmission control means for receiving and transmitting data. A non-fault tolerant input/output module is coupled to transmit the data to the input/output terminals of the fault tolerant data processing module. This module includes a read device for transferring data to the fault tolerant computing system in response to requests from the data transmission control devices, and a firewell for preventing the non-fault tolerant input/output module from initiating transfers of data to the fault tolerant data pro­cessing module.

Abstract: A foamlike pressure-sensitive adhesive tape can be produced by photopolymerization and yet have a dark appearance when dispersed throughout its pressure-sensitive adhesive layer are glass microbubbles to which are adhered dyed, finely divided silica particles. The dyed glass microparticles also are useful as fillers in other articles to which they can impart surprisingly intense coloring. In spite of the good hiding power afforded by the dyed glass microparticles, they do not inhibit photopolymeriz­ing radiation of normally transparent materials into which they can be dispersed.

Abstract: The system employs a coherent detection method for detecting beam interruption between the corresponding emitters (16, 24) and detectors (20, 28) of optical touch panel components that are mounted around a display screen (10). The emitted light signals (17, 25) are modulated coherent with a reference signal. The output signals of the detectors (20, 28) are demodulated coherent with the same reference signal. The demodulated output signals are processed to measure the correlation with the modulated emitted signals. A low correlation indicates the emitted beam was interrupted by a stylus (12) placed near the display screen (10).

Abstract: An improved assisted steering mechanism is described which permits an additional preload to be introduced, in a reduced space and at low cost, on the spring that centers the distributor valve, subsequent to centering that distributor valve. The mechanism that is described also permits the said additional preload to be modified depending on the vehicle speed. 
     This mechanism is made up of two components (1) and (2) which turn on the same shaft E and which are in a relative fixed position on the steering of shaft E. The relative gyration of the two components (1) and (2) determines the opening of the distributor valve. 
     Component (1) has axial enlargements which are inserted in notches pertaining to a spring-washer (6′) which turns solidarily with component (2). The relative gyration of the components (1) and (2) forces the preload of the washer (6′) to be overcome. 
     Force "F" is applied on the washer by joint (16) caused by pressure in chamber A, depending on the vehicle speed. The preload can thus be varied in terms of the speed.

Abstract: In a method for evaluating continuously occurring time markings, from which pulses are obtained, the problem is to eliminate or to reduce the effects of missing pulses or of pulses additionally occurring as interference. According to the invention, a time window is formed at the spacing of successive pulses after the last pulse in each case. Within this time window, the arrival of a further pulse is monitored and, if this pulse does not arrive, an artificially generated pulse is inserted.
